METHOD AND APPARATUS FOR GENERIC MAPPING PROCEDURE GMP AND METHOD AND APPARATUS FOR GENERIC MAPPING PROCEDURE GMP DEMAPPING

摘要

Embodiments of the present invention disclose a method for generic mapping procedure (GMP) mapping, which includes: first the information about a adjusted time slot to be occupied by a second GMP block container is carried in the GMP overhead of a first GMP block container; then, the size of the second GMP block container is adjusted in accordance with the inforamtion; eventually, a client signal is mapped into the adjusted second GMP block container adopting a GMP scheme. This GMP mapping method, when working with a corresponding demapping method, provides lossless mapping and demapping of client signals during the process of bandwidth adjusting.

1. A method for generic mapping procedure (GMP) mapping in an optical transport network (OTN), the method comprising:
carrying, in an GMP overhead (OH) of a first GMP block container, information about a time slot (TS) that needs to be occupied by a second GMP block container subsequent to the first GMP block container, wherein the TS is not occupied by the first GMP block container; adjusting the size of the second GMP block container in accordance with the information; and mapping a client signal into the second GMP block container adopting a GMP scheme.
